Mat_11:10 is not an interpolation by the evangelist (Weizsäcker); on the contrary, it forms the connecting link between Mat_11:9; Mat_11:11. The passage is Mal_3:1, and is a free rendering of the Hebrew and not from the LXX. In Malachi, Jehovah speaks of His messenger going before Himself;here, He addresses the Messiah; before Him will He send the messenger (not an angel). A free application without any substantial change in the contents of the passage, also without any special design in view; comp. remark on Mat_3:3.
